A C-36 plumbing contractor wants to install a solar water heating system. The system includes plumbing connections and electrical components. What licenses are required?
Correct Answer
D) C-36 and C-46 licenses
Solar installation requires C-46 classification. The C-36 contractor can do plumbing connections within their scope, but needs C-46 for the solar system or must subcontract to a C-46 contractor.
Why This Is the Correct Answer
A C-46 Solar contractor license is required to install solar energy systems, including solar water heating systems, because the scope of C-46 covers the full solar system installation. The C-36 plumbing license covers only the plumbing connections within the contractor's scope. For the complete solar water heating system, both C-36 (plumbing) and C-46 (solar) are needed, or the contractor must subcontract the solar portion to a C-46 licensee.
Why the Other Options Are Wrong
Option A: C-36 license only
The C-36 license alone is insufficient. While the C-36 covers plumbing connections, it does not authorize installation of the solar collectors, panels, or the solar system as a whole. Performing solar installation work without a C-46 license constitutes unlicensed contracting.
Option B: C-36 and C-10 licenses
C-36 and C-10 (Electrical) is not the correct combination. While the system has electrical components, a solar water heating system's primary licensing need beyond C-36 is C-46 (Solar), not C-10. The C-46 contractor's scope covers the solar system including its electrical integration, or a C-10 would only be needed if electrical work exceeds what C-46 covers.
Option C: C-46 license only
C-46 alone is insufficient if the contractor is also performing the plumbing connections and wishes to work under their C-36 authorization. The question specifies that the contractor holds a C-36 and wants to do the plumbing connections — both licenses are needed to legally cover both scopes of work.
Memory Technique
C-46 = 'Solar Specific.' Any time 'solar' appears in a question, C-46 is required for the solar portion. The C-36 covers the water pipes; C-46 covers the sun-powered equipment. Think: two systems, two licenses.
